Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613058, here are decompositions:

5 + 31613053 = 31613058
31 + 31613027 = 31613058
67 + 31612991 = 31613058
89 + 31612969 = 31613058
97 + 31612961 = 31613058
107 + 31612951 = 31613058
167 + 31612891 = 31613058
227 + 31612831 = 31613058

Showing the first eight; more decompositions exist.
